Time is the most common and precious. Money can't be bought, and status can't be kept. "Time is the material that constitutes a person's life." Everyone's life is limited. Similarly, the time for a lively event is limited and fleeting.
However, time is precious. Although it limits people's lives, people can make full use of it in their limited lives. Mr. Lu Xun said that time is 24 hours a day, but one day brings wisdom and strength to hardworking people, leaving only regrets to lazy people. I think this sentence vividly describes that successful people cherish every minute and achieve brilliant results, while unsuccessful people just muddle along and kill time because of the idea of "being a monk for a day". In their eyes, time is long and meaningless, but when they look back, they find that time is like running water, gone forever, and they find that time is precious. It can be said that "young people don't work hard, but the boss is sad."
Throughout the ages, many people regret that time flies, so they sigh: "Time flies and makes people old, and the sun and the moon fly like teenagers." Indeed, the speed of time is really difficult to estimate and describe. The tree is dead, and there is still a chance to be green again; Flowers fade and bloom; Swallows have gone and come back; However, if a person's life is over and his limited time is used up, there is no chance of resurrection and salvation. Just as "flowers bloom again, people are no longer young." Time is like this step by step, never to return.
